Three Funds, Same Shares: Is Your Dividend Income Really Diversified?

Owning several funds can feel like diversification. But if those funds hold the same banks and miners, your income may be less diversified than the number of tickers suggests.

Portfolio impact summary

  • VHY, AFIC and BKI can all create meaningful exposure to the same Australian banks and miners.
  • Look-through overlap can make dividend cash flow more sensitive to one sector than your fund count implies.
  • A 30-minute holdings check can show whether your portfolio is diversified by company, sector and income driver.

Why overlap matters for income investors

Diversification is not simply owning more products. Moneysmart guidance is to spread investments across companies, sectors, asset classes and, where appropriate, countries.

For an income investor, the key question is: how many independent sources actually support my cash distributions? Three vehicles may still depend on the same bank dividends, mining earnings and Australian economic cycle.

Three familiar Australian income vehicles

VHY: an ETF with a broad list, but concentrated leaders

Vanguard Australian Shares High Yield ETF (ASX: VHY) owned 92 holdings in the 31 August 2026 factsheet, while its top 10 represented 61.6%. Financials were 38.5% and basic materials 22.7%.

AFIC: a diversified LIC with familiar names

Australian Foundation Investment Company (ASX: AFI) showed BHP at 12.1%, CBA at 7.7%, NAB at 4.1% and WBC at 4.1% in its 30 September 2026 portfolio.

BKI: an income-focused LIC with its own overlap

BKI Investment Company (ASX: BKI) listed BHP at 13.2%, CBA at 6.7%, NAB at 5.1% and WBC at 1.6% in its August 2026 report. Cash was 3.2%.

The look-through example

Suppose an investor puts $10,000 into AFIC and $10,000 into BKI. Using the reported weights, the combined exposure would be approximately:

BHP $2,530 (12.7%); CBA $1,440 (7.2%); NAB $920 (4.6%).

Add VHY or direct holdings and the same names can become a much larger share of both capital and dividend income. These figures are illustrative and use published percentages, not current prices.

What this means for dividend resilience

Overlap does not automatically make a portfolio unsafe. The risk is assuming income streams are independent when they are not. If banks provide 30% of underlying cash dividends and bank dividends fall 20%, the direct effect would be roughly a 6% reduction in portfolio income. This is hypothetical, not a forecast.

A practical 30-minute overlap check

  1. Download the latest holdings for every ETF and LIC.
  2. Normalise company names and combine duplicate tickers.
  3. Calculate the look-through weight for your top 10 companies.
  4. Group the result by sector, especially banks and miners.
  5. Compare it with direct shares and superannuation exposure.
  6. Ask whether one dividend cut would change your household cash-flow plan.

Verdict

VHY, AFIC and BKI can each play a useful role in an Australian income portfolio. But owning all three is not the same as owning three independent income engines. Check the look-through holdings, sector weights and dividend drivers before deciding that your portfolio is diversified.
